The risk benefit analysis

A Typical example:

“I just reached the conclusion that this [thyroid cancer] is one of those things in medicine that we really still don’t understand. I think that the treatment being suggested to me, including radioactive iodine, which will then be absorbed by all of my other organs, is something that I am just not willing to risk. I’m a gambler, so I went towards the other side: I’m going to exercise more, I am going to eat better and I’m going to just watch my body and see what happens.”
